This invention relates tovroller skates in `general and-more particularly'to the trucks of roller lskates.

Among the objects of the present invention theskater dependingto some extent upon his' or her weight whereby the trucks may tbe adjusted not only to rock inva'plane parallel to the shoe support, but also toVv incline to `aline -perpendicular to the shoe support -as a result oi `the movement of the body of the skater so that the pairs of wheels of each truck will leffectively` engage the supportingv oor and therebyY assist a skater. particularly a figure skater, in a smooth and graceful execution of a predetermined figure More-speciically, the-invention aims toprovide an improved-skate such asdisclosed in application for patent filed March 19, 1946,y Ser. No. 655,414, now Patent No. 2,490,849 dated December 13, 1949, which includes a shoe support, a pair of castings, each casting supporting yone 'off the axles, a pair of pins, each iixedto said support and yieldably associated with one of said castings, a second pair of pins, each lxed toone ofsaid castings. two ball connections rockably connected to said support,'each ball connection being yieldably associated with one of said vlsec-V ond pair of pins and one of said castings.

These and other features, capabilities andadvantages of thepresent invention will appear Afrom the subjoined detail"description of one specic embodiment thereof illustrated in the accompanying drawings, in which Fig. l is a plan View of a skate made according to the present invention.

Fig. 2 is a section on the line 2-2 of Fig.. 1.

Fig. 3 is a front elevation ofthe embodiment illustrated in Fig. 1. j

Fig. 4 is-an enlarged section on the line lI-.4

ofFig.3.` 1

Fig. 5 is a section on the line 5-5 of Fig.. 4.

In the embodiment shown, thereis illustrated I and 2 and the bar 3 thus constitutethe supe, port for the shoe. The openings 5 in the present y '-v 4 UNITED 7 `instance bothv are disposed outwardly mia-'longitudinal direction` relativel` tothe openings 6'. This skate is provided with two axles 1 and 8, therear wheels 9 being journalled on the axle "I, and the front wheels II] being journalled on the axle 8.'y Since the -means for connecting the axles 1, 8 to the bar 3 are substantially identical, only one of them will be described in detail. This means or mechanism consists essentially of a casting II in which the axle, such as the axle 8, is journalled. lThis casting has an outermost screw threaded opening I2 toreceive the end I3 of the pin I4 which hasa collar I5 engaging the upper face of the casting II. On thevl` upper lface of the collar I5 there is provided afrubber in the ball- I8. The' ball I8 is rotatably mounted in the concave seat 270'formed in the bushing 2| having the diminishedend 22 screw threadedly connected in theY large openingr 5 of the bar 3.

The casting II is also providedl with aflarge opening 23 having a lower conical portion 24 and an upper annular recess 25 tol receive 'the rubber-louder 426. The rubber buffer 26 Ais chambered to receive the shank'21 of the screw or pin 28'and has a lower conical portion to fit `in vthe seat 24 and an upper cylindrical portion,"=the lower shoulder of which is located in the -annular recess 25 in the casting I I. The upper parto'f the shank 2I. of the screw 28 is screw threaded to receive the large adjusting nut 29, the locking nut 30 and the opening 6 in the bar 3. Prefer;- ably as shown, the upper cylindrical portin3l of the rubber bushing26 has a metal cap 32 .positioned thereon with a central openingto permit the shank 21 to pass therefrom. Preferably also as shown, a wearing washer 33 is disposed between the cap 32 and the main adjusting nut 29, see Figs. 4 and 5. Preferably as shownin Figs. 4 and 5, one side of the shank 2'IA is iiat, see the portion 34, to cooperate with the flat face 35 of the wearing washer 33.. To assemble .this mechanism, after the axle 8 has been xedin the casting I I, the pin I II may be screw threadedly connected thereto, until its collar I5 engages the upper face of the casting I I. Thereupon the rubber washer I6 is slipped over the pin I4, and then the ball I8 slipped on'the .pin I4 untilits head I'I engages the washer I6. Thereupon the bushing 2I is connected to the bar 3.

Thereupon the rubber buier 26 is positioned in -the opening 23, as shown in Fig. 4, the'cap 32 mounted on its upper end, the screwv 28 then vpositioned in the buffer 26, thereupon the washer until it engages the lower face of the bar ,31' and the adjusting nut 29 turned to effect the desired compression on the bushing 26.

The washer 33 due to the cooperation of. the.v

fiat face 34 of the shank 2lv with thei'latface 35 of the washer 33, see Fig.V 5, will be anchored against rotation with the adjusting nut 29, vand consequently the cap 32 protected against wear when the adjusting nut 23 is .turned to Aeiiect the desired compression of the buier 26. The washer 4 ed in said seat, and yieldable means associated with said pins and casting to cushion the blow when the skate strikes the supporting floor in the course of use.

3. A truck for a roller skate including a sup- .port for ashlee, a casting-fior;theaxle Aof a pair and slidable in said casting, a bushing` having a 4concave seat xed to said support, a ball slidably "mounted upon said nrst pin and rotatably mounted in saidseatya yieldable buffer intermediate said second pin and said casting, an adjusting 33 will thus also serve as a lock nut Vto anchor the adjusting nut 29 against accidental displacement after it has once been turned for a predetermined adjustment. V

From the foregoing it will thus be seen that for each truck or for each'connecti-ng means between .the bar 3 and the axlevl or 8,*there is only one adjustable element, to-wit, the Vnut 2 9. This -nut 29 is provided to produce the desired compression'as aforesaid on the buiier 26, which compression will vary depending upon the weight of the skater and the tastefo the skater..Y In the use of a skate provided with this `improved truck or connecting means,A it will be seen that the rubberelements, to wit, the' washers t6- and buifersjd; will at all times cushion the skater` fromgthe 'blow produced whengtheskate strikes the supporting door. Itwill also appear that lthe ballsfjl of the two trucks or connectingmeans will cooperatewith the screws2 constituting king pins togenable the axles of the two pairs of wheels 9 and IG to incline relative to one another, see the dash and dot line position of thewheels Si relative 4to the full line position of the wheels .13, when, as an instance, the skater executes a curve or turn, and that they will also cooperate with one another to enable the axles ofthe'wheels 9 and l to incline relative to the plane of the plates l[fand 21,'.see thedash and dot line position of the wheels H) in Fig. 3, when such turn or'curve is executed.- f l ,v
